Air (Pen Page) [DEFAULT SETTING: Unselected]
This checkbox controls the SmartAIR air-assist function (if you have the optional air compressor installed). By
selecting a pen color and checking this box will enable the SmartAIR air-assist function for that particular pen
color. As an example, if you are performing a combination of both surface raster engraving job and deep vector
cutting on a material such as acrylic, you may want
to enable the SmartAIR air-assist for the vector cutting sections to get the cleanest cuts. To do this, you would
simply need to select the pen color that you have assigned to the sections to be cut and select the Air checkbox
for those particular pen colors.
NOTE
In order to use the Air Delay function under the firmware or the Air assist function in the driver,
make sure that the optional air compressor is connected to the power outlet located in the lower
machine cabinet. There are two power outlets located in the right-hand side of the lower machine
cabinet, make sure that the air compressor is connected to the power outlet towards the left which
is closer to the fuse.
Auto Focus (Pen Page) [DEFAULT SETTING: Unselected]
This checkbox sets the Auto Focus for that particular job. With the Auto Focus button checked, LV-290 will
automatically initialize the auto focus procedure before starting the job. This will ensure the focal distance is
properly set based on the particular material you are working with and the focal lens you have installed.
Defocus (Pen Page) [DEFAULT SETTING: Unselected]
This checkbox enables users to set the Defocus or out of focus distance for a particular job. With the Defocus
button checked, the LV-290 will use the entered focus distance when performing the auto focus procedure
before starting the job. This feature allows users to use out of focus engraving techniques when working with
different types of materials. Note that the Defocus distance is set by the different pen colors.
